+# Architecture
+
+Subtitle Tools is a relocatable React application with a framework-independent
+TypeScript subtitle model. The parser first applies byte/text and line bounds,
+then produces one normalized cue model for SRT, WebVTT and ASS. Operations return
+new documents instead of mutating parser state. Serializers are format-specific;
+cross-format export deliberately exposes its preservation boundary.
+
+Parsing and timing transformations are synchronous in v0.1 and therefore capped
+at 4,000,000 UTF-16 units, 250,000 units per physical line and 100,000 cues. The
+editor renders at most 10,000 cue rows and 2,000 issue rows, while validation and
+export still cover the complete bounded document. Revision comparison is
+index-aligned and linear rather than an unbounded semantic diff.
+
+The optional waveform component uses browser-native media decoding, keeps at
+most 2,000 peak buckets and accepts no more than 128 MiB or four decoded hours.
+It does not run a codec, speech-recognition model or network service.
